ADHD Medication Makes You More Gifted?

I am currently prescribed 72mg of Methylphenidate XR (AKA Concerta) and I believe it bolsters my IQ by about 10 points. When I was 16 I was prescribed Adderall XR 40mg and I coasted through every abstruse discipline without even trying. Honestly, I am such a fervent proponent of ADHD nootropics I believe that they should be legal. It is a travesty that in Japan Adderall is illegal. Who here is on ADHD medication? Do you prefer Amphetamines or Methylphenidate?
